IMPROVEMENT ,1N soDA-FoUNTAIN.

`The Schedule referred to n these Letters Patent and making pari: of the same.

I, ELIsHA BLFoWLEn, of Washington city, in the `District of Columbia,haveinvented certain Improvenient-s in PortableSoda-Water Fountains, of which the following is aspecifoation.

Thenatnrefoff my invention relates to improvements in that class of portable cast-iron soda-water fountains, which require to heconstrncted in suoli a Away as to permit of their being.,r conveniently lined with porcelain `or otherwise coated with' enamel on the inside, so as to protect the metal from the corro- `sive eifect of the soda-water. l l

M y improvenientscousist in a simple and economical methodforuniting thevarions parts, soas to produceperfeetly air-tight fountains, strong enough to resistthe. pressure ofthe gas with which they are charged, the advantages claimed being greateiieconomy in the construction of parts, simplicity in the methods of putting-them together, or in separating them' for repair, or cleaning whereby all Vexistoi' a fountain, cast in one piec'e'fof any convenient 'size or shape, terminating in a neck-shaped projection outhe:top,`and`,openatthe bottom. A shoulder or annular recess, suitable to receive packing, is cast around the bottom of A, and handles or lugsa a', or

`other suitahlejlif'ting device, may be cast or otherwise `secured to the sides. y

B is a anged movable-bottom, into which the body `of' the fountain is itted,'rubber or other suitable packing, K," being inserted between them.

`The piecesA and B, are lined on the inside, with l porcelainor-other enamel.

In the .fountain represented by fig. 1, a boleis cast' or drilled through the neck Aof piece A, and a correspondi'ng hole througbthe center of bottom piece 4B.

Around this latter hole an annular recess may-betast the tube or hollow rodC, which 4is left open at its upper end, whereit is cutwith an external and inter- "nal screw-thread. At-its lower end it is made solid,

- f and cnt with al screw-thread on the outside.v This tube O is made of galvanized iron or other anti-corrosive metal. L

By this method `of construction, the upper end of tube O is screwed into the neck of the fountain, and

- l the bottom piece Bis screwed onto its lower end. A

nut Dis then screwed onto the part projecting below the bottom, a washer, d', or other suitable packing 'being placed between them.

vscrewed onto thel lower end of tube C, thereby accomplishing the same resultwithout requiring the end of tube G to be so made solid.

' H is a small ftube or goose-neck screwed into tube -C,.through the neck of the fountain, far enough to close the holes or slots g.

Thistubeis also firmly secured tothe neck by nut G and packing m, and` is provided with a valve, e.

If desired, the pipe H maybe made toA extepd downward, through tube-G, 'to alevel with the top of holes j, and also, it' desired, the goose-neckmay be made separate, and screwed on above the valve c.

The operation of my improved fountain is as follows:

The body and bottom piece of the fountain, iig. 1,

being castas aforesaid, and lined with porcelain or other enamel, are securely united by the tube C in the manner'described. A suficient quant-ity of water 'is then introduced through the neck, finding its way into the fountain through the holes f, the air escap ing through the holes g.4 Gas from a separate generator of the required strength and volume, is then forced into the wat-er in the same way, and the pipe His then secured in the neck, vwhen thefonntain is ready for use.- By turning the valve c, the pressure of the gas in the upper part of the fountain forces the soda-waterthrougb thelioles f, and up through' the goose-neck in any desired quantity, uut-il the contents ofthefonntain arc completely exhausted.

I do not claim cast-iron fountains of' any particular shape. y

I claiml. `A portable sodafwater, fountain, constructed` as described, in which the tube or hollow rod'C is the channel of induction and eduction, and also'the bond. of union, substantially 'as described andfor the purpose specified.

2.'1n combination with the tube C, as aforesaid, the fountain' A, and movable bottom B, and nut D, substantially as and forthe purpose specified.
